wheel colliders

Has anyone used the wheel collider and achieved descent results with it ?

Yes, it’s actually fairly flexible, although not completely realistic. I used them with Off Roadin’, which is on my blog.

It’s the best example I have seen with the wheel collider. How did you achieve this ? And how would you make the physics feel more earth like?

Off topic. The AI is quite good, I like how it anticipates the next curve - and it’s kicking my a** - how did you achieve this waypoints ?

I think most of the realism comes from setting the friction values way lower. Here’s the setup for the player’s wheel collider (changed very slightly since last release):

I’m kinda-sorta working on a custom Wheel class, which will simulate contact patches, weight transfer, etc, and hopefully will be a lot more realistic and customizable.

As for the AI—yes, they use waypoints. The AI is good for two reasons, mainly: I set up the waypoints very carefully, and the AI car is actually 20% slower than the player car. forwardsAccel = aiSpeed * speed;Where speed is a general modifier and aiSpeed is 0.8. This reduced speed gives them a little more grip and a little less airtime, which lets them get around a bit faster.

Thanks for sharing.
